The practical difference
| Tool | Primary question | Typical evidence |
|---|---|---|
| Network scanner | What is reachable on this local network? | Devices, IP addresses, hostnames, services, ports |
| WiFi analyzer | How is the wireless radio environment behaving? | Access points, channels, signal strength, interference |
| Speed test | How fast is the path to a test server? | Download, upload, latency and sometimes jitter |
What iPhone network scanners can do
After Local Network permission is granted, an app can communicate with devices on the joined network using permitted networking APIs. It can combine responses, hostnames and advertised services into a useful inventory. It can also run application-level tools such as ping-style reachability tests, DNS lookups, traceroute and TCP connection checks.
What iOS limits
iOS does not expose unrestricted passive packet capture, raw radio scanning or every hardware identifier to normal App Store applications. A product claiming to be a “WiFi analyzer” may therefore focus on the current connection, internet performance or LAN devices rather than nearby channel analysis.
Choose by the problem you need to solve
- Unknown device: local network scanner and router client list.
- Host is unreachable: ping, DNS and route diagnostics.
- Unexpected service: targeted port scan on equipment you administer.
- Weak signal in one room: signal/coverage measurement and access-point placement review.
- Slow internet: speed test plus latency and router/ISP checks.
Why Pynqr uses “network scanner”
Pynqr focuses on local device discovery, network identity, open services, security evidence, history and diagnostics. It does not claim to be a replacement for specialized spectrum-analysis hardware or unrestricted desktop packet capture.
